Thanks for the c&p with added pics with even better light down tube, filters are obviously fine as noted previously. And kudos to you for follow up and being above board. May not be popular with louverphobia types, but who cares. And in honor to tyman's all clear, something similar....More added better camera
Old subject here … I ruined some good filters and cut some old filters. You can’t judge them well from the view afforded when fully assembled … think about window blinds flipped one way or the other … or standing on a ladder looking down on window blinds

An excellent reason to buy at NAPA. Plus, you will be able to inspect them before buying.
Wow! I must have been sleeping when that photo was posted. That looks like 2-3 thousandths slits. I'am an old "box opener". I would choose another also if i saw that.
